SPECiFiCATION forming part of Letters Patent No. 614,336, dated November15, 1898.

Application filed March 7, 1898. Serial No. 672,978. (No model.)

To all whom it may concern:

Be it known that I, HENRY L. NORTON, of Middletown, in the county ofMiddlesex and State of Connecticut, have invented a new Sash-Fastener;and I do hereby declare the following, when taken in connection with theaccompanying drawings and the letters of reference marked thereon, to bea full, clear, and exact description of the same, and which saiddrawings constitute part of this specification, and represent, in-

Figure 1, a plan view of a sash having two sash-fasteners embodying myinvention applied thereto; Fig. 2, a view of the left-hand side of myfastener; Fig. 3,a side view with the cap removed; Fig. 4, a sectionalview on the line a b of Fig. 3 with the cap in position; and Fig. 5, aside view with the cap removed, show.- ing the locking-lever in itsretired position.

This invention relates to an improvement in sash-fasteners, andparticularly to that class which are adapted to be attached to the topof the upper rail of the lower sash for engagement with a keeper orseries of keepers in the side of the upper sash or witha keeper orseries of keepers arranged in the side of the window-casing,incontradistinction to fasteners in which the keeper is arranged upon thelower rail of the upper sash;

The object of this invention is to produce a fastener by which thesashes may belocked together when partially open as well as when in aclosed position and one which will require two hands to operate it, orat least one which cannot be operated with one hand by a person outsidethe sash, although the sashes might bepartially open; and it consists inthe construction and combination of parts, as-

will be hereinafter described,and particularly recited in the claims.

The shell or frame will consist of two parts, which for convenience ofdescription I will designate as the case A and cap B, which when rivetedtogether form the complete case. Within the case, upon a collar a, whichis mounted upon one of the rivets b, is hung a locking-lever C, formedat its upper end with a nose D and at its rear with adownwardlyextending leg E, the lower end of which is curved and whichterminates in a toe f, having a flat under surface. The space betweenthe leg E and the body of the lever forms a seat F for one end of aspring G, the other end of which bears upon a partition I-I, formed inthe case. Upon one side of the upper end of the lever,at its inner walland preferably upon the right side, is formed a finger-piece I,whichprojects through a notch J, extending inward from the rear wall of thecase. Opposite the notch J in the cap B is formed a similar but shorternotch J. In the rear of the leg E of the locking-lever is a slide K,guided for transverse movement in the case and formed withaforwardly-projecting arm L, which extends beneath the partition H, bywhich it is guided, and terminates in a downwardly-extending finger M,forming a bearing for one end of a spring N, the opposite end of whichis seated against the rear wall of the case, the tendency of the saidspring being to force the said slide forward. This slide is formed atits inner upper end with a cam-faced projection K, which has afiat upperedge m. It is also provided at opposite sides of its outer end withfinger pieces 0, which project through notches P, formed in the case Aand cap B, and so that the operating-slide may be readily grasped by thefinger. In the normal position the inner end of this slide standsbeneath the leg E of the locking-lever and as shown in Fig. 3. In thisposition the nose D of the locking-lever is adapted to engage with oneof a series of sockets Q, arranged either in the face of the side bar ofthe sash, as shown at the right of Fig. 1, or with the window-case, asshown at the left of the same figure, and in this position it is forcedby the spring G and locked in such position by the engagement of theflat edge m at inner end of the operatingslide with the toe f of the legE. If there is more or less play between the sashes, it will becompensated for by the forward movement of the locking-lever C, which isadapted to move forward until the nose E enters one of the sockets A,and as this lever moves forward the operating-slide K will also beforced inward and so as to lock the lever in this forward position andso that if the fastener is applied to the upper rail of the lower sashfor engagement with the side bar of the upper sash the two sashes willbe locked together and with the upper sash raised or partially lowered.With the addition of a second fastener at the left for engagement withthe window-frame the lower sash will be looked in the desired position,and hence both sashes held in a fixed position. When it is desired tomove the sashes, the slide K must be first drawn outward until theprojection 7.", is in the rear of the toe f, when the lever C may thenbe drawn inward by grasping the fingerpiece I and turning the lever tothe position shown in Fig. 5. If it is desired to retain the fastener inthe opened position, the operating-slide K will be released while thelocking-lever O is held in its retired position and so that under theaction of the spring N the locking-slide will be forced inward and theprojection 70 pass over the toe f, so as to hold it downward, as shownin Fig. 5. When it is again desired to release the locking-lever, it isonly necessary to withdraw the operating-slide K, which will release thelocking-lever and permit it to return to its normal position. It will bereadily seen that the slide and lever cannot be conveniently operatedwith one hand, and as the fingerpiece on the lever O is upon one sideonly it is clear that by no possibility could both parts be operated bya person outside the sash, although the sashes might be sufficientlyopened to allow the fastener to be reached with one hand.

With two fasteners of this character arranged as shown in Fig. 1 it isclear that the sashes may be partially opened and locked together, sothat they may be raised or lowered at the same time, so as to open thewindow at the top or bottom, or the lower sash may be locked in anydesired position, so as to lock both sashes in the closed position orwith either or both of them partly open.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. In a sash-fastener, thecombination with a case, the upper portion of which is open at the frontand back, of a locking-lever piv otally mounted at its lower end in saidcase, and having a nose which projects forward through the front of thecase when in the locking position, said lever adapted to project throughthe back of the case when in the unlocked position, and also formed witha downwardly and rearwardly extending leg, and an operating-slidelongitudinally movable in the case and formed with a projection at itsinner end for engagement with said leg, substantially as described.

2. In a sash-fastener the combination with a case, of alocking-levermounted therein and provided atits upperend with aforwardly-extendingnose and at its rear with a downwardly and rearwardly extending leg, anoperating-slide mounted for longitudinal movement in the case andadapted at its inner end for engagement with said leg, and a notchformed in one side of the case at its upper end, and a finger-piece onthe locking-lever roectin into said notch substantiall 1 as P J adescribed.

3. In a sash-fastener the combination with a case, of a spring-actuatedlocking-lever mounted therein and provided at its upper end with aforwardly-projecting nose and at its rear with a downwardly-extendingleg which terminates in a rearwardly-extending toe, a spring-actuatedoperating-slide transversely movable in the case and provided at itsinner upper edge with an end for engagement with the lower end of saidleg whereby the locking-lever is held in its forward or re tiredposition, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
